I don't see why it would be a big deal. Server developers would have a convention that defines "default" canonical URLs to everything. So http://www.foo.bar/index.html would return http://www.foo.bar/ They would also provide a mechanism for overriding the canonical URL on a per-document basis so that you could state that a particular file is really a mirror of another document. If you don't do that, its a different document. > This doesn't worry me.

I think that there is. I think that it is perfectly reasonable to want to have more than one URL for the same logical resource and allow RDF and XLink attachment to both names for the thing. The most obvious example is in mirroring. > I am doubtful that any canonical-addressing scheme can > combat the human propensity to screw up sometimes. -Tim That's not so much what I'm worried about. I think that having multiple names for a thing can be good practice both because names are human readable and because they are tied to machines. If I am right, then this (reasonable) practice should not mess up the Web's fundamental concept of identity. -- Paul Prescod - ISOGEN Consulting Engineer speaking for only himself http://itrc.uwaterloo.ca/~papresco Alabama's constitution is 100 years old, 300 pages long and has more than 600 amendments.
